https://twitter.com/dommbaddd/status/1244756853634093058 We were talking about how everyone was sick in the last months of 2019 and early 2020. I wonder how many people had corona and didn’t even know. Literally all our kids on the tball team were sick. I got sick in November and had a cough for over a month.
One coworker starts to cough early December last year in my office. Then row by row the cough spread to other coworkers. I caught it later and cough last around 2 weeks. A couple of coworker coughed one month or more. But all my family member's are fine. We talked about the possibility of COVID-19, but one coworker went to doctor office, and said he had flu-A.
如果去年得的，现在抗体还会是阳性吗？
很难讲
